[FR] Add option to update CocoaPods

[amjaliks]

Feature proposal

• EDM4U Component: iOS Resolver

EDM4U has and option to install CocoaPods. However, there is no option to update CocoaPods. A user should use command line to update CocoaPods. For users unfamiliar with CocoaPods and using them only as EDM4U dependency this may be a tricky task.
